Приветствую форумчани, помогите пожалуйста разобраться, не могу запретить ICMP на своем VDS, перепробовал множество инструкций из Google, и машинка все равно пингуется.
Debian 11
UFW
-A ufw-before-input -p icmp --icmp-type echo-request -j DROP - сделал машинка пингуется
# echo “net.ipv4.icmp_echo_ignore_all = 1” >> /etc/sysctl.conf
# sysctl -p - сделал машинка пингуется
# ok icmp codes for INPUT
-A ufw-before-input -p icmp --icmp-type destination-unreachable -j DROP
-A ufw-before-input -p icmp --icmp-type source-quench -j DROP
-A ufw-before-input -p icmp --icmp-type time-exceeded -j DROP
-A ufw-before-input -p icmp --icmp-type parameter-problem -j DROP
-A ufw-before-input -p icmp --icmp-type echo-request -j DROP - сделал машинка пингуется
У меня установлено ядро xanmod, возможно это связанно, и нужно внести изменения в его конфиг, но я не знаю как это сделать.

У меня ubuntu 22.04 с последними апдейтами.
Ровно одна строка для блокировка icmp реквеста
-A ufw-before-input -p icmp --icmp-type echo-request -j DROP

Вот здесь - sudo nano /etc/ufw/before.rules
ufw disable && ufw enable
Ребут и готово.
Кастомное ядро не влияет.
Удачи!

насколько я понимаю, у меня дело в правилах iptables, сначала идёт строка "accept all" а затем только DROP ICMP, если "accept all" переместить в конец таблицы, то по идеи если в трафике будет ICMP он будет отрезаться и проходить дальше, имхо, я ещё совсем новичок, и пытаюсь разобраться 🤷‍♂️
